Ash from dinosaur-era volcanoes might have created fossil fuels.
Thank volcanoes from dinosaur-era for the oil and gas of today.

Ever wonder when were the oil and natural gas deep inside the earth were first created. Well, it seems that the nutrient-laden ash coming from huge volcanoes towards the end of dinosaur-era triggered a series of events which ultimately lead to the formation of these fossil fuels. Scientists noticed that the ash layer seemed to be associated with shale gas and oil deposits and this ash had the same micronutrients as the volcanoes laying the foundation of their theory.
